WFRSG Overview

As permitted by the NERC Standard, BAL-003-2, many Balancing Authorities within the Northwest Power Pool Area have instituted the Western Frequency Response Sharing Group (WFRSG). By collectively participating in the WFRSG, participants are entitled to calculate their annual Frequency Response Measure (FRM) in aggregate to achieve an FRM that is equal to or more negative than its’ (the WFRSG) FRO to assure sufficient Frequency Response is provided to maintain Interconnection Frequency Response equal to or more negative than the Interconnection Frequency Response Obligation.
